BICSI EXAM QUESTIONS AND ACCURTAE
ANSWERS A+ GRADED
Simplex - Answer Transmits signals in only one direction-only listener has no way to
respond, and public address system is example
Half duplex - Answer Transmits signals in both directions but only once at a time-push to
talk systems
Full duplex - Answer Transmits signals in both directions at the same time-telephones
EMI - Answer Electromagnetic interference
Alternating current - Answer 0 ➖ max ➖ 0
(a) Direct current - Answer 0 ➖ max (battery)
RFI - Answer Disturbance in electromagnetic signals
Frequency - Answer Number of cycles a signal is repeated in time period
Bandwidth - Answer Info carrying capacity of a system
Analog signal - Answer Continuously varying signals that follow loudness(AMPT) and
frequency(tone)
, Digital signal - Answer Non-continuous signal that changes from one state to another in
a distinct order
Decibel - Answer Measure of analog signal strength
Megahertz - Answer Bandwidth of system in a frequency range of interest
Megabit - Answer Number of bits of info that can be transported over the media
Resistance - Answer Conductors ability to resist the flow of electrical energy
Inductance - Answer Electrical forcefield around conductor that opposes changes in
current flow
Capacitance - Answer Storage of electrical charges when potential voltages exist
between conductors
Mutual capacitance - Answer Two conductors
Unbalanced capaitance - Answer Conductors and ground
Impedance - Answer Total opposition to current flow (AC circuits)
Characteristic impedance - Answer Input impedance of a uniform analog transmission
line of infinite length
Value of characteristic impedance - Answer -Material & diameter of conductors
-distance between conductors
-insulating values of seperators
